Am I Going Insane (Radio) is a single by the band Black Sabbath on the 1975 album Sabotage. Although common conception is that the suffix "Radio" was said to be added to the title because it was made for the purpose of being played on the radio, drummer Bill Ward said that it was Cockney rhyming slang for "mental"; radio-rental. Critics also have said it was ironic that all the members of Black Sabbath except for Tony Iommi later suffered from clinical depression.
